THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 414,666, dated November 5, 1889. Application filed January 31, 1889. Serial No. 298,278. (No model.) Patented in New South Wales August 9, 1888, N0. 849.

To all whom, it may concern:

Be it known that I, FREDERICK R. WIL- SHIRE, a subject of the Queen of Great Britain, residing at Berrima, in the county of Camden and Colony of New South \Vales,

have invented new and useful Improvements in Thill- Couplings, (for which I have obtained a patent in the Colony of New South "Vales, No. 849, dated August 9, 1888,) of which the following is a specification.

This invention relates to improvements in thill-couplii'igs, the object thereof being to secure in devices of this class, in addition to most effective anti-rattling capabilities, also the features of durability, simplicity, cheapness, and ease of being manipulated for attachment, detachment, or adjustment; and the invention consists in the construction and combination of parts, all substantially as hereinafter described and shown, and set forth in the claim.

Reference is to be had to the accompanying drawings, forming part hereof, in which similar letters of reference indicate corresponding parts in all the views.

Figure 1 is a central vertical section through the coupling and the thill-iron and axle, between which the coupling is applied. Fig. 2 is a plan view of same. Fig. 3 is a View of the under side of the upper pivoted bar of the coupling. Fig. 4 is a plan view of the axleclip or tie-plate, which also forms a portion of the coupling. Fig. 5 is a view in detail illustrative of a modification in construction, to be hereinafter referred to.

The clipA for embracing the axle B is formed and applied as usual, with the exception that the tie-plate a thereof is provided with a forward extension 6, and the U-shaped strap d has a forwardly-extending ear-piece f, and in the present form of coupling the thill-ironD, instead of having a transverse hole in its rear end, is formed bifurcated or U-shaped, and between the ends of the branches e thereof a v cross-pin gis rigidly fixed by riveting or otheror chan nel h, of semicircular cross-section, and

a flatbar G, which by its rear bifurcated ends I is pivoted to the ear-piece of the clip by the pin or rivet m, has on its under side a transverse groove or channel 12., to come, when said bar is swung down, into proximity with the extension I) opposite the said'groove h, and thereby a clam p-soeket is formed for the thilliron pin g. A bolt H is passed loosely through the outer end portion of the pivoted bar G and the extension I), having a screw engage- 6o ment with the latter, and, if desired, a checknut 19 may be applied on the lower end of the bolt against the under side of said extension I) to securely maintain the relation of the parts when in adjustment. The head of the bolt, as 6 5 shown, may be perforated to enable said bolt to be turned by a bar as well as by a wrench. The upper side of the extension b, about the place of the bolts penetration, may be pro vided with a boss 2', formed integrally therewith, of truncated pyramidal or conical form, the under side of the pivoted bar G being correspondingly recessed, as at t. This feature of construction is not essential, but forms an interlocking bet ween the adjacent parts,main- 7 5 taining them and the bolt against lateral strain and displacement, and also insuring a greater length of screw engagement for the bolt, and

thereof. The pin of the thill-iron is inserted 85 in the transverse socket by removing the bolt and swinging up the bar G, when on replacing the bar and tightening the boltthe Walls of the socket are brought to contact, and with suitable pressure on the said pin, it being 0 understood that in con struction the opposing faces of the extension I) and bar G are to be normally separated, as shown in Fig. 1, to permit of the wear compensating adjustment.

\Vhat I claim as my invent-ion is- In a thill-coupling, the strap d of the axle clip having the ear-piece f, the tie-plate a, having the forward extension 12, formed with The ear-piece for the transverse groove h, and in advance opening and provided with a head to bear on thereof the tapered boss 1', having the screwthe top of said bar G, substantially as deto threaded opening, the bifurcated bar G, pivscribed.

oted to said ear-piece formed with the trans- 5 verse groove n, and the tapered recess 25, com- VVILSHIRE' bined WiththG bifurcated thin-iron having Witnesses: the cross-pin g, and the screw-bolt H, having H. E. J OPLING,

its shank engaging said screw-threaded boss- W. QUINN.
